Chapter 12 Cardiovascular System Disorder Flashcards
used to disrupt the function of the sympathetic nervous system they work by blocking impulse transmission at ______receptor sites
adrenergic
a surgical procedure in which two blood vessels, ducts, or other tube-like structures are joined to allow the flow of substances between them
anastomoses
surgical repair or unblocking of a blood vessel, especially a coronary artery.
used to reduce plaques
angioplasty
localized lesions in the heart muscle that may interfere with the conduction
Aschoff bodies
listening for sounds, perhaps with a stethoscope within the body
auscultation
a sensory nerve receptor that is stimulated by a change in pressure, perhaps BP
baroreceptors
abnormally slow heart rate
bradycardia
a heart that is larger than normal size
cardiomegaly
leads to the contraction of the heart muscles and therefor an EKG is an indirect indicator of heart muscle contraction
depolarization
removal of the intima and any obstructive material in an artery
endarterectomy
conduction of impulses produces changes in electrical activity that can be picked up by
electrodes
blood flow in the very small blood vessels (ex. capillaries)
microcirculation
an abnormal sound heard in the heart, caused by a defective valve or opening in the heart
murmurs
difficult or labored breathing when recumbent (lying down) that is usually relieved by an upright position
orthopnea
fainting, temporary loss of consciousness
syncope
